Abstract
INTRODUCTION_
Hemiplegia is the name given to unilateral paresis
of limbs which commonly affects the upper limb more severely
than the lower limb (Stork, 1978). In children
the hemiplegia may be congenital or acquired. The condition
can be present from birth (congenital hemiplegia),
when it may be due to a congenital cystic deformity of
one cerebral hemisphere or possibly to infarction occurring
in utero. AcqUired hemiplegia usually develops
acutely during, the first few years of life as a complication
to a number of postnatal condi tiona (Vial ton,
1975).
The term congenital is self explanatory and related
to prenatal factors (congenital anomalies, prenatal
infections) or to perinatal factors (prematurity,birth
trauma or perinatal infections). The factors underlying
acquired hemiplegia seldom are identified although many
possible aetiologies have been suggested. The most
common pathological cause is infarction due to either
arterial or venous occlusion (Walton, 1975).
